Engine Running -> Wings On / Wings Off?

[mndless]

Wings on, wings off... sorry, couldn't resist...

Mr. Miyagi say WING ON or you fuselage feel like this!

I tried flying one time without them, but our runway just wasn't long enough to take off.

Runway was long enough, your engine just didnt have enough power.

No doubt. Wings on.

OK, this is deep, but here goes ->
If I put the wings on, and don't start the engine, is there still vibration?

Now this one has been plaguing me for awhile;
If a man is walking in the woods, and there's no woman around, is he still WRONG

I have a VVRC40 twin which is an amazingly smooth running engine and I still put the wings on if going to run.

Wings on

First run, wings off on a shock absorbing setup

Ahhhh...Electric Setups are great!! Wings Off, Grasshopper.

Seems like it depends on what the weak link in your airframe is. Wings off has higher natural roll resonance frequency, might match better to engine vibrations. Wings on lowers frequency, might match better to engine vibrations. Wings off results in higher amplitude motion of the airframe on the planes I own and have watched, but I don't know if that means more stress or not for anything other than the gear and whatever else is holding the airframe. Wings on adds more vibe time on the wings. Certainly wings off is rougher on your ears (and your hands if you are physically holding the airframe). Don't know that I have ever been able to trace an airframe problem to engine vibrations on the ground from either configuration. But since it is more comfortable wings on, and since they have been developed to operate wings on, that would appear to be the most sensible way to go.
